Problems solved by technology

[0006] Since multiple encryption cards may be encryption cards of different manufacturers, that is, the processing performance of different encryption cards may not be consistent. Therefore, when the data is evenly distributed to each encryption card, the processing performance of each encryption card cannot be fully utilized, that is, Said that the processing performance of the cryptographic card cannot be maximized

Abstract

The present application provides a parallel computing method, device and equipment for heterogeneous cipher cards. The method includes: determining the target data length corresponding to the service to be processed, and querying the initial weight ratio corresponding to the target data length from the weight table; for each cipher card , determine the amount of data that the encryption card needs to process based on the initial weight ratio, and send the data to be processed that matches the data amount to the encryption card; wherein, for each data length, the initial weight ratio corresponding to the data length is Determine based on the initial weight corresponding to the data length of each encryption card; for each encryption card, determine the initial weight corresponding to the data length of the encryption card based on test data generated during the testing process of the encryption card. Through the technical solution of the application, the processing performance of each encryption card is fully utilized.

Description

technical field [0001] The present application relates to the technical field of data security, in particular to a parallel computing method, device and equipment for heterogeneous cryptographic cards. Background technique [0002] In order to effectively protect data, when data is stored, it is necessary to store the data after encryption, and correspondingly, the encrypted data also needs to be decrypted before use. During data transmission, the data needs to be encrypted before transmission, and correspondingly, after receiving the encrypted data, it also needs to be decrypted and used. [0003] Considering that both data encryption and data decryption require a large amount of computing resources, a cryptographic card is usually integrated in the device to realize data encryption or data decryption. As a kind of hardware encryption card and hardware decryption card, the cryptographic card can improve data encryption or The processing speed of data decryption has been wi...
